Hydrazones are a family of organic compounds with a composition of R 1R 2C = NNH2. We are linked to ketones and aldehydes by substituting oxygen for the NNH2 functional group. They are normally formed by the action of hydrazine on ketones or aldehydes. The production of aromatic hydrazone derivatives is used to quantify quantities of low molecular weight aldehydes and ketones, e.g. in gas streams. For example, dinitrophenylhydrazine coated on silica sorbent is the basis of an adsorption cartridge. Hydrazones are then elucidated and analyzed by HPLC using a UV detector.
